Optical computation of the divergence of a vector field using a metal-dielectric multilayer
Leonid L. Doskolovich, Artem I. Kashapov, Evgeni A. Bezus +1
We theoretically describe the optical computation of the divergence of a two-dimensional vector field, which is composed by the transverse electric field components of an incident…

Topological properties of reflection zeros of optical differentiators based on layered metal-dielectric-metal structures
Artem I. Kashapov, Evgeni A. Bezus, Dmitry A. Bykov +2
We investigate the topological properties of reflection zeros of three-layer structures consisting of a dielectric layer sandwiched between two metal layers, which can be used as o…

Vectorial spatial differentiation of optical beams with metal-dielectric multilayers enabled by spin Hall effect of light and resonant reflection zero
Leonid L. Doskolovich, Artem I. Kashapov, Evgeni A. Bezus +1
We theoretically describe and numerically investigate the operation of "vectorial" optical differentiation of a three-dimensional light beam, which consists in simultaneous computa…
